The effect of selenium deficiency on the fatty acid metabolism of rats and lambs

Creator:: Fischer, William Carl
Abstract:: Selenium deficiency in rats results in increased carbon metabolism, approaching twice the rate of selenium supplemented animals (normal). This is also reflected in a 50 percent increase in lysosomal enzyme activity in tissues of selenium deficient animals. Isolation of rat liver lysosomes shows a 17 percent increase in membrane thickness...
